Just had an idea for a rushing solution don't know if its been suggested or not...
before you start playing the game, you select rush, farm, exp farm, etc. if someone wants to rush, they join a game thats labeled rush. if someone wants to farm, they join a game labeled farm, and etc.
(been suggested i guess but still good idea so feedback anyway)
(also credit to arterra and snakespeare and whoever else suggested this too)
